Answer:
400.5 m
Step-by-step explanation:
To avoid any confusion regarding the width of the track itself affecting the perimeter value, the problem is asking you to find the perimeter of the white inner area only. We know that the straight parts of the track has a total length of 212 m (= 2 x 106 m). If we ignore the straight parts, note that the ends are nothing but two halves of a circle or radius 30m (= 60/2 m) where circumference is
C =2(pi)r = 2(3.14)(30m) = 188.5m
Therefore, the perimeter is
P = 212 + 188.5 = 400.5 m

−x−86<7
Answers
Answer:
x<-94
Step-by-step explanation:
-x-87<7
Add 87 to both sides, thus canceling it out.
-x-87<7
+87 +87
-x<94
The x can't have a negative. So we divide -1 from it.
-1x<94
/-1 /-1
x<-94
---
hope it helps
Answer:
x > -93
Step-by-step explanation:
-x - 86 < 7
=> Add 86 on both sides of "="
-x < 93
Since -x could also be written as -1x, divide both sides of "=" with -1 so x becomes positive, since we are dividing by a negative number the inequality sign switches:
x > -93

On a certain hot summer's day,432 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled 664.50How many children and how many adults swam at the public pool that day?
Answers
Answer:
399 children, 33 adults
Step-by-step explanation:
Children = c
Adults = a
c + a = 432
a = 432 - c
1.5c + 2a = 664.50
1.5c + 864 - 2c = 664.50
-.5c + 864 = 664.50
-.5c = -199.5
.5c = 199.5
c = 399
432 - 399 = 33
a = 33
Answer:
kids = 399
adults = 33

What is the surface area of this triangular pyramid?
Answers
Answer:
here you go
Step-by-step explanation:
To find the slant height of triangular faces: The slant height of a triangular pyramid is generally represented by 's'. Add all the areas together. Thus, the surface area of a triangular pyramid formula is 1⁄2(a × b) + 3⁄2(b × s) in squared units.
The surface area of this triangular pyramid is 10.908 in².
We have,
Base of Triangle= 3 in
Height of Triangle= 3 inch
P = 3 inch
h = 4 inch
Now, slant height= √4² + 1.5² = √16+2.25 = 4.272 inch
So, the Surface Area of Triangular Pyramid
= base Area + 1/2 x 3 x 4.272
= 1/2 x 3 x 3 + 6.408
= 4.5 + 6.408
= 10.908 in²
Thus, the surface area of this triangular pyramid is 10.908 in².

Answer:
x = 25º, right scalene triangle
Step-by-step explanation:
The interior angles of a triangle add up to 180º.
The red square indicates the angle measure is 90º.
We are left with two other angles, x and (2x + 15).
Let's set up an equation to represent the angle measures
90 + x + (2x + 15) = 180
First, combine like terms.
90 + x + 2x + 15 = 180
105 + 3x = 180
Subtract 105 from both sides to isolate x.
3x = 75
Divide both sides by 3 to further isolate x.
x = 25º
Let's check our answer by plugging it back into our original equation.
90 + x + (2x + 15) = 180
90 + 25 + (2(25) + 15) = 180
Simplify.
90 + 25 + (50 + 15) = 180
90 + 25 + 65 = 180
115 + 65 = 180
180 = 180
Your answer is correct.
x = 25º
Now we need to classify the triangle.
As stated before, the red square indicates the angle measure is 90º. This means our triangle is a right triangle.
Because the other two angle measures are different from one another, we know that the side measures cannot be equal. This leaves us with a scalene triangle.
Your answer is: right scalene triangle

Choice B) As x decreases, y decreasesChoice C) As x increases, y approaches 0Choice F) The function is an increasing function=====================================================
Explanation:
The graph has a negative y-intercept. So for example, we could have a y intercept of (0,-1) or (0,-2). The x value is always 0, and in this case, the y coordinate is some negative number.
Due to the negative y intercept, this means the function curve is below the x axis at this point. The common ratio r, such that 0 < r < 1, tells us that the exponential function is decreasing in absolute value. Let's say the y intercept was (0,-10) and the common ratio was r = 0.5
The common ratio of r = 0.5 means the second term is r*(first term) = 0.5*(-10) = -5, and the third term is r*(second term) = 0.5*(-5) = -2.5
The terms: -10, -5, -2.5 show us that they are decreasing in absolute value, but in terms of a graph, they are going upward toward zero.
So that's why as x increases, so does y (which makes it an increasing function). And y is approaching y = 0. However, it never actually gets to y = 0.
On the flip side, if x is decreasing, then y is also decreasing. Both x and y increase or decrease together in any increasing function. A decreasing function would have x increase while y decreases, or vice versa, meaning they go in opposite directions.

16x - 16 = 4( ? )
A 4x - 4
B 4x - 16
C 2x - 2
D 12x - 12
Answers
Answer:
A since if we multiply 4 × 4x, we get 16x, and 4 × 4, we get 16, which cancels with the other 16x - 16 on the left side. That makes sure that any x we choose will cancel out in the end.
Step-by-step explanation:
1. 16x - 16 = 4(4x-4)
2. 16x - 16 = 16x - 16
3. 0 = 0
4x16 - 16 = 48
16x4-16=48
